Tarvulogian Author and founder of the Scottish Rationalist Tarvuist Assembly. Her books, many of which are subtitled 'A Sensible Approach to Tarvuism', aim to discount some of the more incredible claims in the Tarvunty. For example, she believes that Tarvu's Great Swims (where he sometimes remained underwater for weeks) should be interpreted metaphorically and not as literal fact.

In her non-religious life, Lenny also is one of the world's most prolific collectors of cats and owns more than 1,000 - each one of a different breed - including a mountain lion and a puma (who have had their teeth removed). In the late 90's, she was romantically linked to Hollywood actor Brad Pitt.
